Calcium and Parathyroid Hormone Disorders

Normal calcium level is critical for proper functioning of almost all cells and organs of body. Calcium level in blood is tightly regulated by parathyroid hormone. Parathyroid hormone is produced by parathyroid glands, which are situated behind the thyroid gland in the posterior part of central neck.

High calcium level can be asymptomatic and silently damages bones and cause kidney stones. High calcium level can present as fatigue, muscle aches and pains excessive thirst and excessive urine production. High calcium level is usually due to enlargement of one or more of the parathyroid glands, however sometimes high calcium level can be due to invasion of some cancer cells to bones.

Low calcium level can cause tingling, numbness of hands, feet, around the mouth and slurred speech. It can be due to low parathyroid hormone levels or very low vitamin D levels.
